To be honest...that link is not the pistol you want, it’s a plinker...you really want the older Hämmerli pistol with the longer barrel, and target sights. That’s the pistol for Bullseye. Call Larry’s in Maine.

a New Sig is hard to find and $800 is not a bad deal for one.. I've seen the used 6" models on gunbroker for around 600.. you just have to wait on them. The X-esse (Walther version of the same pistol) runs around $1000.
